Hi everyone i have a friends July 1994 KH 1.6 litre ford laser hear and i need to change the auto gearbox in it as it has lost all gears except for 1st. I just bought another July 1994 Kh laser for the auto gearbox and have just noticed that this one is a 1.8 fuel injected model. does anyone know if the gearbox from the 1.8 will fit the 1.8

The 1.8 trans code is k
The 1.6 trans code is b

If anyone has any information please let me know
Thank's
